1 Full lift safety valve with spring loading. (AIT) EP Model 5 Model 5 Model 95 AP ES AS EP AP ES Model 5 Model 5 EP AP ES AS Model 95 The valve works as an automatic pressure releasing regulator activated by the static pressure existing at the entrance to the valve and is characterized by its ability to open instantly and totally. Design in accordance with ASME code section VIII. Materials according ASME code section II and ASTM. Connections according ASME B.0. standard.. In accordance with the requirements of directive 9/3/CE. EC valve verification certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. EC Type (Module D) EC examination report nº certified by: TÜV Internacional Grupo TÜV Rheinland, S.L. In compliance with the ATEX 9/9/CE directive Protective equipment and systems for use in potentially explosive atmospheres. Other authorisations: ISCIR, ITI, NASTHOL,...etc. AS ASME Catalog available in International System Units (SI) in PDF format. Características 90 angular flow. Activated by direct action helicoid spring. Simplicity of construction ensuring minimum maintenance. Materials carefully selected for their resistance to corrosion. Internal body designed to offer favourable flow profile. Sealing surfaces balanced and making them extremely tightness, even exceeding API-5 requeriments. Great discharge capacity. For liquids typically used with openings similar to proportional safety valves. Auto-centering plug. Totally precise open and close. All the valves are supplied sealed at the set pressure requested, simulating operational conditions, and are vigorously tested. All components are numbered, registered and checked. If requested in advance, material, casting, test and efficiency certificates will be enclosed with the valve, and the instruction manual, in accordance with P.E.D.9/3 EC.
